Theimain members of the. grinding" mill consist of atruncatedconeshapedshell 23,

made of cast iron or some other suitable. mate.- rial, and is adaptedto.- be. rotatably-mounted on the supporting bracket portion 5.:in anysuitable manner such asby the ball bearings '24: Lock or set screws. 25areadapted to extend loosely through outwardly extending. "lug portions26 from theballiibearingrace member. 26. .forthe purpose of holdingthe{race firmly in positionfon thesupporting 4r member 5,. after. it hasbeen properly.loca-ted by means of adjustingscrew 25, The. numeral 25designates a plurality of set screws adaptedto he mountcdin suitable lugpriortions securely. attached to-the plat-e mom her 5, and arranged insuch amannerthat theshcll 23-n1ayloe given sideway adjust. ability bythe proper operation of: the set screws 25, the ball bearing supportingmembeisfii being slidablypositipned on the plate 5. Theinn-ersurfaceoftheshell 23is provided with a detachable corrugatedplate27,

connected ,with the surface in some suitable manneras by tap. screws28..- Securely' fastened. to; the outer periphery of: the: shell 23 bymeans of elements 29. is a gear member 30,

Idapt'edato cooperate-and mesh with a driving gear member 31,securely-keyed toa shaft ele1nent.32,-which is mounted in a journalbearing 33: attached to the supporting memher 2 by means of plate 34'.

The upper end of the shaft.3.8.is rotatively mounted in abearing 44:,

whichisifastened to the frame member 7 by means. of bolts 450i;otherwise. In the lower port-ionof the. shaft 38 is preferably secured alongitudinal key member 4 6-, which should be ofzs'uflicient; length toreceive in keyed rela-, tionship to ,the shaft a driving'pulley 47,adapted tobe driven from some suitable source of. power by means of aplate 48, a sprocket wheel or pulley 49 for driving the shaft 32, theshell member 23,.and' the paddle. 17. Thesprocketwheel 19 is. adapted tocooperate with wheel member 50, keyedto the shaft32,the wheel memberslQ-and 50 be-.

ing operably connected by means of a chain or other suitable element 51.I I

The shaft 38 hassecurely,mounted thereon inoperative alignmentfwiththeshell 23 a.

truncated cone. shaped member 52 having attached to,itsouterperiphery asuitable corrugated plate 53, which is in normal operation spaced: fromand in} alignment with-the cooperating corrugated-plate 27 on, the.shell. inember23;.; Theplate 53-is detachably con-.

nected, to. the truncated; cone shaped-member 52 by, meansjofisu-itable. fastening members 54 Securely attached to5 the uppersurface of-the .trun,cated coneshaped member 52 isa (loyv wardlyi andoutwardly inclined mein- 7 her 55, having attached thereto a pluralityof distributing or supporting elements 56 for the purpose .ofreceivinganddistributing the rain from the sp0ut-18,,just beforeit-enters between the corrugated grinding members 27 .and 53.

In the, lower portion. -of. the, shell member 23 isadaptedto be locateda paddle .member 57, keyed to the shaft-38by means of key 46, andadapted to revolve therewith. The pad -dle 57'is provided with adownwardly extended sleevebearingi 58, which revolvesfreely in abracketqournal 59, fastenedto the frame or supporting plate member 5.

Froman opening 60 in the plate 5, is adapti 7 ed to extend a deliveryspout 61 Y for the ground grain, which is guided into the chute onspout:61 by means of therevolvingpaddle member 57: The driving pulley 47sprocketwheel..i9;: and-.paddlemember 57' are positioned upon the shaft38 in suchaalmannerthat:

the shaft 38 may have easy adjustability upwardly and downwardly as maybe desired without disturbing the relative position of the drivingpulley 47, sprocket wheel 49 and the paddle 57, which are retained inoperative position by means of bracket members 62, 63, or otherwise, andthe supporting plate for the paddle element 57.

In this construction it is readily apparent that the plate 5 functionsin part as a bottom plate member for the shell 23, the lower edge of theshell being suitably located in relationship to the plate member 5 inorder to allow for the desired sideway adj ustability of the shell 23,it being understood in this respect that the sideway adjustability isintended to keep shell 23 in perfect alignment with cone member 52.

In order to provide means for giving upward and downward motion to theshaft 38 and incidentally to the truncated cone member 52, it ispreferred that the rod element 40 be mounted at each end in adjustableelements 66 and 67, which are arranged to receive in securedrelationship therein manually operated rod members 68 and 69, providedat the lower ends with gears 70 and 71, securely keyed thereto andadapted to mesh with and cooperate with gear members 72 and 7 3, keyedto shaft 7 4, which is mounted in the supporting members 1 and 2, asdisclosed at 7 5 and 7 6.

The upper ends of the rods 68 and 69 may be provided with hand wheels.77 and 78. Suitable bracket journal elements 7 9, 80, 81 and 82 aresecurely fastened to the frame members 1 and 2 for the purpose ofmaintaining the rods 68 and 69 in rotative position. By turning thewheels 77 and 78, it is apparent that the threaded portions 83 and 84 onthe rods 68 and 69 will cause the rod 40 to move upward or downward asdesired, thereby functioning to provide the required adjustability inthe position of the corrugated plate 53, the set screws 25 and 25 alsofunctioning to produce cooperating adjustability in order to obtain themost efficient spacing and alignment between the two corrugated surfaces27 and 53,.

V The rod 40 is securely mounted thereon adjacent the frame supports 1and 2. Guiding members 85 and 86 adapted to cooperate in slidablerelationship with guiding rail members 87 and 88 are attached to theframe supports 1 and 2, thereby providing efficient means for positivelyguiding the rod 40 and the shaft 38 in its upward and downward movementwhenever the hand wheels 77 and T8 are revolved.

This invention provides a vertical grinding machine particularly adaptedfor grinding corn, oats, rye and the like into feed for farm animalssuch as cattle, horses, hogs and other stock.
